Yes, absolutely it does. My home (and the homes and/or businesses of others I am in touch with) is infested and we are currently ripping out every inch of the wool insulation - a project that is costing an eye watering six figure sum.
We have Thermafleece. Since mid 2005 Thermafleece has been treated with borax but we bought our product in the early 2000's when it first came to market and was treated with diatomaceous earth. In my experience is absolutey, categorically not moth-proof. In fact, my pest controller (who has treated other Thermafleece infested properties) tells me he thinks the infestation is so heavy, even in areas where the product is pretty much sealed up in internal walls, that he can only conclude the moths were in the material prior to installation.
I have got nowhere with the manufacturer, Second Nature UK Ltd, as they are uninsured for this problem - their original insurer had withdrawn cover and I believe the new policy doesn't cover product failure of this nature. They liquidated this summer leaving creditors with little chance of covering their legal fees. let alone any money towards the cost of remoingl and replacing the Thermafleece. In the meantime, they established a second business that has run concurrently with Second Nature for two years. This new business, Eden Renewable Innovations Ltd, sells Thermafleece, it operates from the same premises as Second Nature UK Ltd and has the same directors.
So, the bad news is that if you bought Thermafleece from Second Nature UK Ltd or one of their suppliers the liquidation of the compnay means you will not receive compensation from the manufacturer. You will also not be able to claim on your insuarnce: moths are classed as pests and pest damage is not covered by any form of household (buildings or contents) insurance.Lastly, the BBA certifcation the original product held (and revised new product has) is worthless for it is neither a guarantee of warranty, despite the misleading statements on the BBA's webste that suggests their evaluation process assesses if a product os fit for purpose and will last the life of the building (60 years). Our Thermafleece did not last 6 years, let alone sixty and cost us a six-figure sum.
This supposedly 'green' and ethical product has cost us a fortune, has required multiple skips sent to landfill with the moth and larvae filled Thermafleece, plus chemical spraying of the whole house, inside and out, after removal (not to mention all the chemical spraying that has taken place over the years), There has been more environmental damage in removing the stuff than its green credentials could ever make up for.
I wish I could be more positive when answering your question. The only solace I have gained whilst on this nightmare of a journey was discovering I am far from alone in my experience. Support from the others as we each destroy and then rebuild our homes has helped me see some light in an otherwise very dark tunnel.
